Mozilla: Analysis Maturation Plan, Content Security Policy and Firefox Reality

Filed under
Moz/FF
  • Analysis Maturation Plan

    To summarize the problem, I need to be able to share analyses with my peers at Mozilla (often HTML documents generated by Rmarkdown). Currently, we effectively dump documents onto an FTP server tied to a webserver (called Hala). This works pretty well, but it makes it almost impossible to search and discover other people's analyses and makes getting review difficult.

    To address these two problems, we put together mozilla.report and mozilla-private.report. These are effectively lightweight blog indexes for public and private analyses. This works OK, but it still requires analysts to take the time to check in their results and get review. It's a little heavy weight and isn't getting as much use as I would like. Hell, I don't even use it all the time just because I'm busy.

  • Test the new Content Security Policy for Content Scripts

    As part of our efforts to make add-ons safer for users, and to support evolving manifest v3 features, we are making changes to apply the Content Security Policy (CSP) to content scripts used in extensions. These changes will make it easier to enforce our long-standing policy of disallowing execution of remote code.

    When this feature is completed and enabled, remotely hosted code will not run, and attempts to run them will result in a network error. We have taken our time implementing this change to decrease the likelihood of breaking extensions and to maintain compatibility. Programmatically limiting the execution of remotely hosted code is an important aspect of manifest v3, and we feel it is a good time to move forward with these changes now.

    We have landed a new content script CSP, the first part of these changes, behind preferences in Firefox 72. We’d love for developers to test it out to see how their extensions will be affected.

  • Discover on desktop or mobile. Enjoy in VR, only with Firefox Reality.

    A special update for Firefox Reality is available today -- just in time for the holidays! Now you can send tabs from your phone or computer straight to your VR headset.

    Say you’re waiting in line for your festive peppermint mocha, killing time on your phone. You stumble on an epic 3D roller coaster video that would be great to watch in VR. Since you’ve already signed in to your Firefox Account on Firefox Reality, you can send that video right to your headset, where it will be ready to watch next time you open the app. You can also send tabs from VR over to your phone or desktop, for when you eventually take your headset off.

    When you use Firefox on multiple devices, you can sync your history and bookmarks too. No more waving the laser pointer around to type wonky URLs or trying retrace your steps back to that super funny site from yesterday. Stay tuned in the new year for more features like these that make using VR a more seamless part of your everyday life.

  • Tiny i.MX6 UL DIN-rail computer has dual mini-PCIe slots

    Axiomtek’s compact, rugged “Agent200-FL-DC” DIN-rail computer runs Linux on a low-power i.MX6 UL. Features include 10/100 Ethernet, USB, serial, DIO, optional CAN, and 2x mini-PCIe with a SIM slot.

    Axiomtek has posted product details for a “coming soon” Agent200-FL-DC DIN-rail computer. Like last year’s similar IFB125 and the IFB122 from 2017, the Agent200-FL-DC is a headless gateway that runs a Yocto based Linux stack on NXP’s 528MHz Cortex-A7 based i.MX6 UltraLight (UL) SoC. This time it’s Yocto 2.4 “Rocko” running on a newer Linux kernel 4.9.88. This is the only one of the three that also supports Ubuntu 18.04 (with the same kernel), as well as Android 8.1.

  • Huge Coffee Lake Refresh system has four PCIe slots for Nvidia and AMD graphics

    Vecow’s rugged, Linux-friendly “GPC-1000” computer has 8th or 9th Gen CPUs with up to 64GB DDR4 and provides 4x PCIe slots that support dual-slot graphics.

Mesa 19.3.0 Released

Graphics/Benchmarks
  • Mesa 19.3.0 Release Notes / 2019-12-12

    Mesa 19.3.0 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 19.3.1.

    Mesa 19.3.0 implements the OpenGL 4.6 API, but the version reported by glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. Some drivers don't support all the features required in OpenGL 4.6. OpenGL 4.6 is only available if requested at context creation. Compatibility contexts may report a lower version depending on each driver.

    Mesa 19.3.0 implements the Vulkan 1.1 API, but the version reported by the apiVersion property of the VkPhysicalDeviceProperties struct depends on the particular driver being used.

  • Mesa 19.3 Released With Big Updates For Intel's Open-Source Drivers, Valve ACO Option

    After a few weeks worth of delays due to blocker bugs the release of Mesa 19.3 is out today as a big end-of-year upgrade to the open-source OpenGL and Vulkan drivers for Linux systems. Intel and AMD Radeon driver changes largely dominate the work as always but there is a growing number of embedded driver changes and other enhancements for this crucial piece to the open-source 3D ecosystem.

  • Circuit Python at PyConf Hyderabad

    Coding in/with hardware has become my biggest stress buster for me ever since I have been introduced to it in PyCon Pune 2017 by John. Coding with hardware provides a real-life interaction with the code you write. It flourishes creativity. I can do all of this while I learn something new. Now I look for auctions to offer me a chance to code in/with Hardware. It gives the chance to escape the muggle world.

  • New in testmon 1.0.0

    Significant portions of testmon have been rewritten for v 1.0.1. Although the UI is mostly the same, there are some significant differences.

  • Determining affected tests

    Automatically determining affected tests sounds too good to be true. Python developers rightfully have a suspecting attitude towards any tool which tries to be too clever about their source code. Code completion and symbol searching doesn't need to be 100% reliable but messing with the test suite execution? This page explains what testmon tries and what it does not try to achieve.

    [...]

    After running the test with coverage analysis and parsing the source code, testmon determines which blocks does test_s.py::test_add depend on. In our example it's Block 1,2 and 4. (and not Block 3). testmon doesn't store the whole code of the block but just a checksum of it. Block 3 can be changed to anything. As long as the Block 1,2 and 4 stay the same, the execution path for test_s.py::test_add and it's outcome will stay the same.

  • How to set-up and use py.test in Pycharm

    I've been using Vim and terminal as a weapon of choice for years. I've had a good time with it, however, more and more people ask me why I'm using this setup. And honestly, I don't know the answer.

    I'm aware that things can be done more efficiently and an IDE can help with a lot of things. I guess that my weak spot is the unit tests and testing my code in general. I'm not running my tests when on the coding spree, I'm breaking lots of stuff, and only when I think I'm finished, I'll do the fixing and make everything running green again.

    Well, I would like to change that. And I'm also curious about trying out new ways of doing things. The obvious choice for programming in Python is the PyCharm. It's a nice IDE, supports many features that I like and most importantly, it can help with the testing. PyCharm can easily integrate with popular test frameworks and run the tests for me.

Vim 8.2 is available!

Software

Before I did the keynote at VimConf 2018 I asked plugin developers what they wanted from Vim. The result was a very long list of requested features. The top two items were clear: Popup windows and text properties.
After more than a year of development the new features are now ready for the Vim crowds. Popup windows make it possible to show messages, function prototypes, code snippets and anything else on top of the text being edited. They open and close quickly and can be highlighted in many ways. More about that below.

This was no small effort. Although the existing window support could be used, popup windows are different enough to require a lot of extra logic. Especially to update the screen efficiently. Also to make it easy for plugin writers to use them; you don't need to tell Vim exactly where to show one, just give a reference point and the text to display, Vim will figure out the size and where the popup fits best.

Text properties can be used for something as simple as highlighting a text snippet or something as complicated as using an external parser to locate syntax items and highlight them asynchronously. This can be used instead of the pattern based syntax highlighting. A text property sticks with the text, also when inserting a word before it. And this is done efficiently by storing the properties with the text.

The new change listener support can be used to keep the highlighting up-to-date and support other LSP features. An example of what can be done with this is the "govim" plugin. It connects to a server (written in Go) and uses "gopls", the Language Server Protocol (LSP) server for Go. You can find a list of features with links to demo videos on github. A couple of screenshots are below.

Deepin is a rising star among Linux distributions, thanks to its combination of an elegant desktop environment with the stability and reliability of Debian.

  • Fully supported Unity Editor for Linux delayed, Unity 2019.3 in the final testing stages

    Two bits of big news about the Unity game engine to share today, one specifically about Linux and one about the Unity engine as a whole.

    Firstly, remember the team at Unity announced back in May that the Unity Editor for Linux was going to be fully supported instead of staying experimental? Well, sadly the release date slipped. Still happening though! In an update to the original blog post announcing it, they said it's been pushed from 2019.3 and so it's now happening in 2020. No exact date or version number for when it happens is being given. When we get more news about the Unity Editor getting a date again to move from experimental to supported, we will let you know.

The security of web-based applications is of critical importance. The strength of an application is about more than the collection of features it provides. It includes essential (yet often overlooked) elements such as security.

Kali Linux is a trusted critical component of a security professional’s toolkit for securing web applications. The official documentation says it is “is specifically geared to meet the requirements of professional penetration testing and security auditing.“ Incidences of security breaches in web-based applications can be largely contained through the deployment of Kali Linux’s suite of up-to-date software.

  • Xs:code launches subscription platform to monetize open-source projects [Ed: This is basically about making proprietary software add-ons, betraying Free software premises]

    Open source is a great source of free tools for developers, but as these projects proliferate, and some gain in popularity, the creators sometimes look for ways to monetize successful ones. The problem is that it’s hard to run a subscription-based, dual-license approach, and most developers don’t even know where to start. Enter Israeli startup xs:code, which has created a platform to help developers solve this problem.

    “Xs:code is a monetization platform for open-source projects. Unlike donation platforms which are pretty popular today, xs:code allows open-source developers to provide added value in exchange for payments. That comes on top of what they offer for free. This added value can be a different license, more features, support services or anything they can think of,” Netanel Mohoni, co-founder and CEO of xs:code told TechCrunch.

    This does not mean the open-source part of this goes away, only that the company is providing a platform for those developers who want to monetize their work, Mohoni said. “Companies pay for accessing the code, and they enjoy better software created by motivated developers who are now compensated for their work. Because our solution makes sure that the code remains open source, developers can continue accepting contributions so the community enjoys better code than ever before,” he explained.

    Using open source code comes with a responsibility to comply with the terms of that code’s license. The goal of ACT is to consolidate investments in these efforts and to increase interoperability and usability of open source compliance tooling. Google, Siemens and VMware are among the companies helping to underwrite and lead this collaborative work.

  • If you ARIA label something, give it a role

    As a rule of thumb, if you label something via aria-label or aria-labelledby, make sure it has a proper widget or landmark role.

    The longer version is that several elements created extraneous amount of announcements in screen readers in the past that were not really useful. Especially in the ARIA 1.0 days where a lot of things weren’t as clear and people were still gathering experience, this was an issue for elements or roles that mapped to regions, multiple landmarks of the same type on a page, etc. Therefore, best practice has become to label both widgets (which should be labeled anyway), and landmarks with means such as aria-label or aria-labelledby, to make them more useful.
